A brave Irish teenager who overcame her battle with cancer has finally had her chance to celebrate with a special bell-ringing ceremony.

Shauntelle Tynan, 19, from Tullow, Co. Carlow travelled to Houston in Texas last year to continue her fight against the rare cancer hystiocytosis-x after a massive fundraising appeal raised money for her treatment.

Recently, the youngster was declared cancer-free and on Friday, she took to her YouTube channel to explain the significance of ringing the bell.

She said: "Basically, it's the biggest thing you can do on your cancer journey, it's something that signifies the end of your cancer journey, you're ringing the bell because you're done treatment or you're cancer-free."

The emotional teen added: "We've all seen me go through times where we didn't even know if I would have a future never mind the ringing the bell."

"We can’t thank you all enough for your support and the incredible Doctors and Nurse’s at who have got Shan to this point!! You will never know how much you all mean to us".

An emotional clip shows an overjoyed Shauntelle ringing the bell before hugging friends and family and presenting her doctor with the $10,000 cheque.

Her family paid tribute to brave young Dublin boy Gavin Glynn who lost his cancer battle in 2014, adding that she "rang that bell a little heavier for one little special guy who we never got to meet but his legacy and his family helped us to get here."

Shauntelle will now return to Ireland in three weeks' time along with her family.
